How to Use Composite Docks

:: Composite Dock ::

A CompositeDock is a Dock that contains other docks. It does not contain dockables. The child docks can also be composite docks.

If you want to use a composite dock, you have to do the folowing things:

• Create your dockables.
• Create the child docks for the composite dock.
• Add the dockables to the child docks.
• Add the child docks to the composite dock.

:: Split Dock ::

The most used composite dock is the SplitDock. This composite dock can contain 0, 1, or 2 child docks. When there are 2 child docks, they are split by a divider. In the folowing example a split dock is created with one child dock:

		// Create the child tab dock.
		TabDock tabDock = new TabDock();
		
		// Add the dockables to the tab dock.
		tabDock.addDockable(dockable1, new Position(0));
		tabDock.addDockable(dockable2, new Position(1));
		tabDock.addDockable(dockable3, new Position(2));
		tabDock.addDockable(dockable4, new Position(3));

		// Create the split dock.
		SplitDock splitDock = new SplitDock();
		
		// Add the child dock in the center of the split dock.
		splitDock.addChildDock(tabDock, new Position(Position.CENTER));

In the folowing example a split dock is created with two child docks:

		// Create the child tab dock.
		TabDock leftTabDock = new TabDock();
		TabDock rightTabDock = new TabDock();
		
		// Add the dockables to the tab docks.
		leftTabDock.addDockable(dockable1, new Position(0));
		leftTabDock.addDockable(dockable2, new Position(1));
		rightTabDock.addDockable(dockable3, new Position(0));
		rightTabDock.addDockable(dockable4, new Position(1));

		// Create the split dock.
		SplitDock splitDock = new SplitDock();
		
		// Add the child docks to the split dock.
		splitDock.addChildDock(leftTabDock, new Position(Position.LEFT));
		splitDock.addChildDock(rightTabDock, new Position(Position.RIGHT));
		splitDock.setDividerLocation(290);

		// Add the child docks to the split dock.
		splitDock.addChildDock(leftTabDock, new Position(Position.TOP));
		splitDock.addChildDock(rightTabDock, new Position(Position.BOTTOM));
		splitDock.setDividerLocation(190);

:: Float Dock ::

A special composite dock is the FloatDock. This dock is not a java.awt.Component. Its child docks are the docks in floating windows.

If you are working with a FloatDockModel, then you don't have to create the float dock by yourself. This model creates a float dock for every owner window that you add. You can retrieve this float dock with the folowing code:

		// Get the float dock. This is a standard dock of the floating dock model.
		FloatDock floatDock = dockModel.getFloatDock(windowId);

		// Add the child docks to the float dock.
		floatDock.addChildDock(singleDock1, new Position(x, y, 0));
		floatDock.addChildDock(singleDock2, new Position(x + 50, y + 50, 1));

		floatDock.setDockPriority(DockPriority.CAN_DOCK_WITH_PRIORITY);

:: The Child Dock Factory of the Composite Dock ::

A composite dock has always a DockFactory to create its child docks.

When you drag a dockable above a composite dock and you release the mouse, then the dockable can be added to the composite dock. The folowing things will be done by the docking functionality:

• A child dock is created with the child dock factory.
• The dockable is added to the child dock.
• The child dock is added to the composite dock.

• The child dock factory of a FloatDock is a SplitDockFactory.
• The child dock factory of a SplitDock is a LeafDockFactory.

	floatDock.setChildDockFactory(new SingleDockFactory());

:: Composite Line Dock ::

A special composite dock is a CompositeLineDock. It organizes its child docks in a line.

In the folowing example 2 horizontal composite line docks are created. They have a TabDockFactory as child dock factory.

		// Create the composite line docks.
		CompositeLineDock lineDock1 = new CompositeLineDock(
				CompositeLineDock.ORIENTATION_HORIZONTAL, true, new TabDockFactory());
		CompositeLineDock lineDock2 = new CompositeLineDock(
				CompositeLineDock.ORIENTATION_HORIZONTAL, true, new TabDockFactory());
		
		// Add the child docks to the composite dock.
		lineDock1.addChildDock(tabDock1, new Position(0));
		lineDock1.addChildDock(tabDock2, new Position(1));
		lineDock1.addChildDock(tabDock3, new Position(2));
		lineDock2.addChildDock(tabDock4, new Position(0));
		lineDock2.addChildDock(tabDock5, new Position(1));
		lineDock2.addChildDock(tabDock6, new Position(2));

:: Composite Grid Dock ::

Another special composite dock is a CompositeGridDock. It organizes its child docks in a grid.

In the folowing example a composite grid dock is created. It has a SingleDockFactory as child dock factory.

		// Create the grid dock.
		CompositeGridDock gridDock = new CompositeGridDock(new SingleDockFactory());

		// Add the child docks to the composite dock.
		gridDock.addChildDock(dock1, new Position(0));
		gridDock.addChildDock(dock2, new Position(1));
		gridDock.addChildDock(dock3, new Position(2));
		gridDock.addChildDock(dock4, new Position(3));
		gridDock.addChildDock(dock5, new Position(4));
		gridDock.addChildDock(dock6, new Position(5));
